Start a hosted GroupServer site with OnlineGroups.net
The open source web-based mailing list manager GroupServer is developed by OnlineGroups.net, where you can start a hosted online groups site, powered by GroupServer.
A hosted site will give you all the features of GroupServer without the administration costs. OnlineGroups.net takes care of system updates and administration, and keeps the mail flowing.

A site of your own
With OnlineGroups.net your groups, and only your groups, are on a site with no ads. You can customise the site for your organisation and use your own domain on the site.
As many groups as you like
On your site, you can start as many groups as you like. The groups can be public or private. Your site members can be in as many groups as you like.

Online groups work with email
Online groups work with email, just like listservs: when a group member emails the group, the group sends the email to the group members.

Online groups work on the web
Posts are also stored on your online groups site. You can search and read posts, and files, on the web. And you can post messages and files from the web.
